A couple of days trying things out.
Eliminated are Roxio EMC9 and the Easy Audio Capture. Picking the Stereo Mix option gives me a message "Could not open Sound Device. (Stereo Mix (IDT High Definition). So, that leaves 2 choices on the E A Capture - the 2 mics, Internal and External. As we know the internal isn't good enough so the external is what I try next. I don't have the right lead handy but anticipate no problem from the Line Out ( I will use the headphone socket) to the mic in when I am receiving the radio I want.
Unless something goes drastically wrong when I try it, that will be my method in future and I'll settle for it.
Many, many thanks for all you interest and advice.
PS. The cheque (check) is in the post.
